--- title: "NEO+ PA/VA EN 54-16" description: "NEO+ is a public address and voice evacuation system EN 54-16 based on IP audio with AES67 technology and advanced features" url: https://lda-audiotech.com/en/neo-plus/ date: 2024-04-02 modified: 2026-11-03 author: "LDA Marketing" image: https://lda-audiotech.com/wp-content/uploads/2024/03/LDA-NEO-Plus-featured.png type: page lang: en --- # NEO+ PA/VA EN 54-16 # ADVANCED IP-BASED EN 54-16 PUBLIC ADDRESS AND VOICE ALARM SYSTEM NEO+ is an advanced EN 54-16 certified public address, background music and voice alarm system that offers maximum flexibility and power, with high‑performance features that put it at the forefront of state‑of‑the‑art technology.Designed for medium to large installations, NEO+ reduces time and costs thanks to its plug‑and‑play philosophy, which facilitates all installation, maintenance and system operation procedures. ## EVOLUTION IS WRITTEN WITH + #### This is NEO+, designed with large projects in mind ### Certified, reliable and robust The NEO+ system is certified according to the international standard EN 54-16. NEO+ is reliable and effective in fire safety installations, robust and highly durable equipment in any large-scale project. NEO+ also has other international certifications such as Civil Defense in the Middle East or EAC. ### Scalable and easy to use NEO+ follows the plug-and-play philosophy that reduces installation and maintenance costs by including everything needed to manage a public address and voice evacuation installation in a single unit. It can be easily scaled up using 4- and 8-channel NEO+ Extension units to reach up to 1024 zones in a single system. In multi-controller mode, NEO+ can work without zone limitation. ### AES67/Dante® Technology The NEO+ system features a communications module with AES67 layer 3 technology for encrypted digital audio transmission. This protocol allows interoperability between different systems based on audio over IP, in addition to being an open standard that can be used without relying on more expensive proprietary technologies. ### Dual redundant controller NEO+ incorporates redundant controller functionality to back up the core of the system and secure it against any type of failure or incident in the installation. Two NEO-8060+ main controllers can be connected in a ring so that one operates as the main unit and the second as the backup unit. ### EVAC Control: EN 54 local management and supervision EVAC Control is a local management and monitoring platform for NEO+ and NEO public address and voice alarm systems. Through an industrial hardware server, it enables users to control public address and background music functions, as well as schedule pre-recorded messages using an event calendar. In multisite projects, each independent site requires its own EVAC Control or EVAC Cloud device. Multiple sites can be accessed individually from a single PC. ### EVAC Cloud: EN 54 remote connection and supervision EVAC Cloud enables remote monitoring and alarm management for NEO+ and NEO systems, as well as secure access to advanced configuration functions through NEO Configurator. In multisite installations, each independent site requires its own EVAC Cloud or EVAC Control device, and multiple systems can be accessed from a single PC. ## FRONT PANEL WITH TOUCH INTERFACE FOR SMOOTH AND EASY OPERATION #### Intuitive use and full control from the central unit ![neo_slider-min](https://lda-audiotech.com/wp-content/uploads/2024/03/LDA-NEO-8060-plus-front.png) 4.3″ colour touchscreen display Display with dark mode and access control to the main functions of the system. Fast and intuitive use with icons and without text. Front monitoring speaker Integrated front monitoring speaker for listening to audio inputs, zone routing and pre-recorded messages. Supervised emergency microphone Integrated high-quality, supervised Push-to-Talk (PTT) microphone (connection and capsule). Internal digital audio matrix 8×8 audio matrix (up to 1024 zones), allowing any of the inputs to be routed simultaneously and independently to any of the zones. Dual pre-recorded message player NEO+ has 4 Gb of internal memory to store over 600 minutes of pre-recorded messages that can be played manually or automatically. Up to two messages can be played simultaneously to different zones. +**4.3″ color touchscreen display** Display with dark mode and access control to the main functions of the system.
